Do one thing each day

Instead of being a source of constant distraction, your computer should help you accomplish what's most important to you every day
It's easy to spend hours sitting in front
of a computer immersed in doing little things, while avoiding the most important one.

Its presence at the top of your screen in a place of primacy, near the time, is intended to bring your focus back to what is most important for the day, to make your primary goal present in your computer screen and life.
